Cash out any time ยท provably fair
Mines is a grid of tiles with a number of hidden bombs you choose yourself. The board is 5x5 by default, and you can pick any size from a tight 3x3 up to a 10x10 field of 100 tiles. Every safe tile you reveal pushes your multiplier up, and you can bank your OSRS GP at any point. More bombs means a steeper climb and a shorter expected run, so the whole risk curve is yours to set before the first click.
The multiplier after each safe pick is the exact inverse of the odds of having got that far, with a flat house edge taken off the top: the chance of surviving k picks on a board with m mines is a straightforward hypergeometric, and the payout is the inverse of it, less that edge. That's why a nearly full board pays enormously for a single tile and why a 1-mine board takes a long run of picks to be worth anything. It isn't a designed paytable, it's arithmetic.
The same rule runs on every board size. A 3x3 board and a 10x10 board both pay the inverse of the odds of your run, less the same edge, so the size you pick only changes how the risk is shaped, never how fair it is.
The bomb layout is committed before you touch the board, so the game cannot move a mine under a tile you were about to click. Rotating your seed reveals the server seed and lets you regenerate every board it produced, whatever its size.
Mines is the game most players use to build a manual risk ladder, because it is one of very few where you set the volatility yourself without changing the house edge at all. Three mines and five mines, on a small board or a big one, carry exactly the same edge.
No. The edge is flat, the same on every board from 3x3 to 10x10 and on every mine count. It is applied once to the multiplier formula, so more mines or a different board changes your volatility without increasing the edge against you.
Whichever volatility you want, since the expected value is identical. Low mine counts give long, slow, frequent small wins; high counts give rare large ones.
Yes. One Mines bet can pay at most 50,000 Fire Tokens' worth, which is converted to OSRS or RS3 GP at the live rate when you play in gold. Once a round reaches it the game tells you to cash out.
Yes, and that's the point. Every round is generated from a server seed that is hashed and shown to you before you bet, combined with a client seed you control and an incrementing nonce. When you rotate your seed the old server seed is revealed, so you can replay every round it produced and confirm nothing changed after the fact.
Stakes are in Old School RuneScape gold (or RS3 GP), traded in game with a real host - not a token you can't cash back out.
